Abstract: HOME HEATING SYSTEM DRAFT CONTROLLER                       ABSTRACT        A forced air heating system having a dedicated supply duct for delivering heated air to the heated portions of the building and having an open air return system which uses the rooms, hallways, door openings, etc. of the building for returning air back to the furnace  for  reheating  and  recirculating.    The elimination  of  a  dedicated  return  air  duct significantly improves the distribution airflow volume and thereby the efficiency and comfort of the central heating and air conditioning.  The system includes a flue draft controller which monitors the flue draft at all heating appliances, such as furnaces, hot water heaters, etc., and servos a damper in a single main flue serving all appliances to optimize the flue draft for all  appliances.    If the  flue draft becomes inadequate in any appliance, the controller shuts down heating appliances, as well as all heating system circulation fans, power fans and building exhaust fans which can affect the flue draft.  The controller also enables building safety devices, such as smoke and combustible  gas  detectors  to  shut  down  heating appliances when a building safety problem is detected.

IPC: H04L29/02
Filed: 1990-11-02
Abstract: ABSTRACT      A data representation and protocol are provided to interface two networks.  A plurality of information units to be transmitted from one network to another are formatted into a variable size block in accordance with the protocol.  Each block contains a header field storing a total information unit count and a control information unit count.  The remainder of the block stores the actual information itself, both control and data, in consecutive byte locations, with the actual control information located at the end of the block.  The block can then be sent to another network for processing.  A device in the other network need only reference the block header to determine whether the information contained in the block is control or data.  This speeds the processing of large quantities of either all data information and/or control information.

Abstract: A method and apparatus for controlling the reciprocation of a movable mirror of an interferometer used in an interferometric spectrophotometer are disclosed, wherein a frequency dividing ratio corresponding to a desired reciprocating speed of the movable mirror is set and then a pulse signal from an oscillator is divided at the frequency dividing ratio for producing a frequency-divided signal which in turn is compared with an interference signal from a control interferometer to produce an error signal for controlling the reciprocating speed of the movable mirror based on this error signal until the desired reciprocating speed is reached.      Preferably, the frequency dividing ratio can be varied by a central processing unit, for example, so that the user is able to freely change the reciprocating speed of the movable mirror to conform to the type of a detector used, thereby enabling a measurement under optimum conditions.

Title: System for assigning discrete time periods for dye applicators in a textile dyeing apparatus
Inventor: COX STEVEN W
IPC: D06H1/02
Filed: 1991-02-14
Abstract: A control system for a textile dying apparatus processes and distributes digitally encoded pattern information. A substrate is moved on a path along which the surface of the substrate comes into operative range of a plurality of arrays arranged along the path of the substrate. Each of the arrays has a plurality of individual dye applicators capable of selectively projecting a stream of dye onto a predetermined portion of the substrate corresponding to a pattern element in a pattern composed of a pattern element matrix with a plurality of pattern elements in each of a plurality of pattern rows. Each pattern element is associated with a visually distinct pattern area. The dye applicators project dye for a time period determined by the pattern information. The method first determines a set of initial values. From the initial values it generates a firing command matrix having, for each dye applicator in each array, a firing command sequence corresponding to the pattern element to which that dye applicator may apply dye in each pattern row. Finally, the method allocates, for simultaneous transmission to each dye applicator in each array, the firing command sequence in the firing command matrix corresponding to the pattern element in the pattern row to be applied to the predetermined portion of the substrate that is passing within operative range of the dye applicator at the time of transmission.
